IWTS-30 LCR In-Wall Theater System Speaker
Home Theater Placement
Home Theater Systems
Today’s home theater systems require you to place six or more speakers in your room.
For the most convincing theater effects, speaker placement must be very carefully
thought out. This is especially true with in-wall speakers, since their installation is
permanent!
Left/Center/Right Locations The front three speakers should be at or just above ear
height when seated, just as with stereo speakers. Try to keep the vertical position of
the three front tweeters within 18 inches of each other, as this will maintain smooth,
believable left-center-right pans.
Sometimes, people like to use the Center channel 30 LCR
in its horizontal orientation. If so, rotate the MTM baffle
90 degrees so that the midrange-tweeter elements are
vertically-oriented. (See page 3 for more info on the tilt-
able baffle.)
This ensures the best sound coverage of the listening area,
and most importantly, it maintains identical acoustic radia-
tion patterns from all three LCR speakers—critical for the
best sound.
The spacing of the left-right speakers can be a little wider
than with 2-channel stereo speakers, since in a theater sys-
tem, the center channel speaker reproduces the on-screen
effects and anchors the center image. Left-right spacing of
about 8 to10 feet usually works well.
NOTE: The IWTS-30 LCR is not magnetically shielded.
If you are using it with an old-styled CRT-type tele-
vision, be sure the speakers are located at least 12
inches away from the picture tube to prevent video
interference.
Surround Speakers In order to achieve optimum perfor-
mance, we strongly recommend Atlantic Technology Dipole
or TriVector™ surround speakers. If you are using our dedi-
cated surround speakers please follow the placement recom-
mendations included in their installation instructions.
Non-Dipole Surrounds The most realistic surround effects
occur when the listener can’t localize the actual location of
the surround speaker. If you decide to use conventional
direct-radiating speakers as surrounds, make sure they don’t
point directly at the listening area. One good location for
direct radiating surrounds is above and slightly behind the
listening location, firing straight across the room, or angled
slightly towards the rear wall.
Left Center Right
Subwoofer
Front Speaker Array should be
placed as close to ear level as
possible.
Optional Dipole/Bipole
Speakers should be
placed directly to the
sides of the seating area
and approximately
1-2 feet (.3-.6 meter)
above the listener’s ear
level.
Optional Surround Back Speakers
should be placed approximately 1-2 feet
(.3-.6 meter) above the listener’s ear
level. Direct radiator or dipole/bipole
speakers may be used here.
Optional Direct Radiator Speakers
should be placed slightly behind the
listening position, above ear level.
